RadiativeNZ looks at the Jaxx ROCCO 5.1 Dolby Digital/DTS Sound system. It
seems to be an alright setup, here's their thoughts.
Performance via the analogue input the speakers performed adequately, as
you would typically expect from a sub/satellite system there is a lack of mid-range
frequencies, which was not unexpected, and I thought that the bass was boomy,
somewhat loose, and seemed to suffer from a lack of power. The boomy and loose
nature of the bass probably stems from the fact that the woofer enclosure is
plastic and the port seems overly large for a 4" driver. A wooden enclosure
would have given a better reverberation and a smaller exhaust port would have
tightened the bass quite a bit.
